Broncos’ Randy Gregory among 4 players who will sit out training camp start

New Broncos outside linebacker Randy Gregory will be among at least four players who will not participate in Wednesday morning’s first practice of training camp.

Joining Gregory on the physically unable to perform list Tuesday were receiver KJ Hamler (knee/hip) and right tackle Billy Turner (knee). Rookie linebacker Christopher Allen (foot) was placed on the non-football injury list. All players still count toward the 90-man limit and can be activated at any time.

Gregory underwent shoulder surgery after signing a five-year, $70 million contract and sat out the entire offseason program.

“Randy has been working really hard; he’s had a really good summer,” general manager George Paton said Tuesday. “Obviously there is some work to be done, but we expect him to be on-schedule for Week 1 (at Seattle on Sept. 12) and we’ll see if we can take him off (the PUP list) before then.”

Hamler, who tore his ACL in Week 3 of last year, did individual drill work during the summer practices. Turner had offseason knee surgery and Allen has a non-football injury designation because he wasn’t injured in an NFL game (last September while playing for Alabama).

The Broncos received good health news on other players who were injured during the offseason program. Outside linebacker Jonathon Cooper (finger), tight end Greg Dulcich (hamstring) and receivers Seth Williams (unknown) and Tyrie Cleveland (foot) were not placed on the PUP list.

Single-game tickets. The Broncos will put single-game tickets on sale Aug. 2 at 10 a.m. The limited inventory includes ADA, full- and half-price and United Club seat tickets via Ticketmaster.

The limit for full- and half-price tickets is four per household per game. A total of 2,000 half-price tickets ($15 apiece) will be available (four per household) and will be delivered to the buyer’s mobile device on the day of the game and can’t be re-sold or transferred.

Practice begins. The Broncos’ first training camp practice is scheduled for 10 a.m. Wednesday, the first of four consecutive days of non-padded workouts. The parking lot opens at 8 a.m. and the gates to the grass berm at 9 a.m.
